1. At the end of Duel Terminal, does Gem-Knight Crystal go to the afterlife or does he go on a journey?

Yugipedia's trivia on "Zefra Providence"(final card of Duel Terminal) says that he goes to the afterlife but the Duel Terminal master guide I read said that he set out on a journey. Though, he was hinted to "rest eternally".

2) Fool of Prophecy

During the endymion invasion, when he is infected by darkness, is the book evil or was it just corrupted by a spirit that proceeded to possess Fool? (Spellbook of the Master)

3) Void Trap Hole

The 3 ice dragons are shown to be being sealed, supposedly. I can't really distinguish them apart, could someone who sees it properly outline each of the dragons in the pic and post in comments please?

4) Fabled's have their own realm?

Either this, or they are sealed underground because they are constantly referred to as arriving on the "surface". Which one is it?

5) Jurrac living in a Forest

This one's a bit silly, but anyway, if the Jurrac are on fire, how do they live in a forest?

​

I've got more questions but they can wait until these are cleared.

EDIT: Could someone link me with the World Legacy/Mekk Knight lore?
